Offical Faction Role Question thing - faction that can construct??

[nOmnomnOm]

Here is the issue.
Of course if there is no other option then I could go to a faction that is likely to maybe have some knowledge in building and ask for help.
But I am rather focusing on seeing if there is a faction that in lore has some experience in construction.
Since DHC is not available and DSE is out of the question, I am looking for any other possibilities.
I suppose Kisiro or samura could suffice but Samura from I understand trades.
From what i understand as well kishiro focuses on technology and not building.
Those are two separate fields from construction. I would be surprised if the company would be able to realistically without any other outer help build a space base on their own like this.
With Junkers, I do not want to have a base plated with scrap Jokes aside though, they are probably my last choice along with Zoners. Though I'd pick zoners over junkers in my situation.

Are there any zoners that would actually be able to do something like this renovating base idea? Perhaps TAZ? I've already checked OSI and with little success.
